RSS Toolkit for ASP.NET

The Microsoft ASP.NET team have released a pretty nifty add-on toolkit for VS 2005 ASP.NET 2.0. Scott Guthrie has a nice step by step pictorial tutorial on his blog.
The RSS toolkit includes support for consuming as well as publishing RSS feeds in ASP.NET applications.
Features:

RSS Data Source control to consume feeds in ASP.NET applications

Caching of downloaded feeds both in-memory and on-disk (persisted across process restarts)
